Verification and Troubleshooting Commands: Run also the command “write standby” to save the config to the secondary device. Connect to the primary unit and issue the command “write memory” to save the configuration. “Beginning configuration replication: Sending to mate” ……….Īll configuration commands will be done on Primary unit from now on. From that point on, whenever a failure occurs on the active device, the standby device comes up as active.Īfter the above is completed, configuration replication will start with the following message: The primary ASA stays up and passes traffic normally and marks itself as the active device. After you issue the failover command on the secondary device, the secondary device immediately pulls the configuration from the primary device and sets itself as standby.

Note: Issue the failover command on the primary device first, and then issue it on the secondary device. !Assign IP addresses to Stateful Failover interfacesĪsa(config)#failover interface ip state 192.168.4.1 255.255.255.0 standby 192.168.4.2 In this documentation, the “state” (interface name for GigabitEthernet0/2.2) is used as a State In this documentation, the “failover” (interface name for GigabitEthernet0/2.1) is used as a failover interface.Īsa(config)#failover lan interface failover Ge0/2.1 During Failover the primary IP address will be assigned to Standby Unit.Īsa(config-if)# ip address 192.168.2.1 255.255.255.0 standby 192.168.2.2 During Failover the primary IP address will be assigned to Standby Unit.Īsa(config-if)# ip address 192.168.1.1 255.255.255.0 standby 192.168.1.2 Note: Always start with the active ASA first. They can share the same connection/interface. Note that you don’t have to use two different connections for Failover and State. The Outside interfaces on ASAs are Ge0/0 and LAN interfaces are Ge0/1.įor Failover we will use Ge0/2, particularly Ge0/2.1 will be the Failover interface and Ge0/2.2 the state interface (by which the information about protocol States will be exchanged). Let’s consider an example of active/standby Failover configuration (see diagram below).

If any of these requirements is not satisfied, then they cannot work in failover mode. There are some predefined device requirements for allowing two ASAs to work in Failover mode: both of them must be the same model, both must have the same type and number of interfaces, the same volume of RAM and FLASH, the same licenses and the versions of ASA IOSs of both ASAs must match. State Information for Security Service Module.HTTP connection Table (unless HTTP Replication Enable).HTTP Connection Table (if HTTP Replication enabled).Layer2 Bridge Table (if Transparent mode enabled).The active ASA sends the state information of the following protocols/tables to the Standby ASA: When failover occurs, both ASA devices will have knowledge about all connections. During Stateful Failover however, the active unit continually passes per-connection state to standby unit. During regular Failover, when Failover occurs, all active connections will be dropped. Therefore you should dimension each ASA device in such a way so that to be able to handle all traffic.ĪSA failover works in 2 modes: Stateful Failover and Regular Failover. Configuration Replication is NOT performed from Standby unit to Active unit.Ĭonfigurations are no longer synchronized.ĭuring active/standby failover, the active ASA receives all traffic flows and filters all network traffic while the secondary ASA is in the Ready mode.
